Question: Can Viral Infections Cause Nerve Damage?

What happens when your immune system attacks your nervous system?

This leads to weakness, numbness, and tingling, and can eventually cause paralysis..

Can you have a virus in your brain?

Can flu affect the brain?

The infections also activated the brain’s immune cells in this region for an extended period and altered the expression of genes implicated in disorders including depression, autism and schizophrenia. These findings suggest that some strains of the flu may pose a threat to healthy brain function.

How does a viral infection make you feel?

Often, a person will experience symptoms that may include a runny nose, coughing, nausea, fatigue, and body aches. While not every person experiences a fever when they have a virus, a fever can be a sign that the body is trying to fight off the infection.

What viruses affect the brain?

Encephalitis is most commonly due to viruses, such as herpes simplex, herpes zoster, cytomegalovirus, or West Nile virus. It can occur in the following ways: A virus directly infects the brain. A virus that caused an infection in the past becomes reactivated and directly damages the brain.

Can the flu cause neurological problems?

Influenza can be associated with various neurologic problems: encephalopathy (a state of confusion), seizures, neuropathy, as well as others. These complications most frequently occur in children, although cases of neurologic illness associated with adult influenza certainly occur.

What is severe nerve damage?

Peripheral neuropathy, a result of damage to the nerves outside of the brain and spinal cord (peripheral nerves), often causes weakness, numbness and pain, usually in your hands and feet. It can also affect other areas of your body.

Can a viral infection affect the brain?

Can a viral infection cause a stroke?

Is Radiculitis caused by a viral infection?

Herpes zoster radiculitis or cranial neuritis (shingles) results from a reactivation of varicella-zoster virus infection. After primary infection, the virus becomes latent in sensory ganglia. More than 90% of adults are seropositive for antibodies against varicellazoster virus.
